Detects ChatGPT Enterprise app authentication events that link a third-party app to a user or workspace. Linking apps establishes durable OAuth-style access that adversaries can use to persist connectors after initial compromise.

Detection logic

Its licence does not clear it for publishing here

Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.

The rule states no platform. This is derived from the ATT&CK technique it maps to.

Known benign triggers

  • Common Google Drive/Gmail and Slack connector app_id values are excluded; other sanctioned connectors may still alert.
  • Users legitimately connect approved apps during onboarding.
